- one for 10Mbps and another for 100Mbps traffic. An internal Ethernet switch, consisting of a 10Mbps and a 100Mbps switching port, is used to link the repeater buses. Data will be forwarded to the other internal repeater bus under these three conditions: 1) when traffic has to be passed between a 10Mbps and a 100Mbps device;... -

Fast Ethernet Dual-Speed Hub stack of only two units can easily meet the networking needs of most small to medium-sized workgroups. As your workgroups gradually expand, just add more hubs to your stack, or uplink to another hub or switch using ordinary straight-through cable. -
Page 8: Chapter 2 - A Quick Overview Of Networking
A Quick Overview of Networking Terminology Chapter 2 - A Quick Overview of Networking Terminology Network Terminology A network is comprised of multiple interconnected nodes. A node can be a computer, a server (that is, a computer dedicated to storing network data or appli- cations), a shared peripheral (such as a printer or modem) or other networking devices (such as repeaters or switches, routers, transceivers, etc.). - Page 9 Chapter 2 - continued hub to another hub or switch. By uplinking different hubs or switches together, the number of nodes in a network can be increased. Expanding a network is neces- sary when planning to increase the number of computers connected, or when plan- ning to offer new services, such as printing capabilities or Internet access.

Page 10: Chapter 3 - What Is Fast Ethernet
Chapter 3 - What is Fast Ethernet? Historical Background Fast Ethernet was developed in the early nineties as an answer to the bottle- necking problems encountered by older Ethernet networks. Ethernet is a network- ing technology that was developed in the early seventies. Ethernet networks carried data signals through thick passive cables at a 10Mbps speed. - Page 11 Chapter 3 - continued known as a shielded twisted-pair (STP). Ordinary wire to the home is unshield- ed twisted-pair (UTP). Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for Ethernet and Fast Ethernet networks. 10BASE-T : requires Category 3, 4, 5 unshielded twisted-pair (UTP-3, 4, 5) or Category 1 shielded twisted-pair (STP-1), or any equivalent cable to transmit data.

Page 12: Chapter 4 - How To Configure A Fast Ethernet
Uplinking Uplinking a hub with another network expansion device, such as a router, switch, bridge, or repeater hub allows users to increase the number of ports on a network. A 100BASE-TX hub can be uplinked with another 10BASE-TX/100BASE- TX hub through a twisted-pair cable. This is an easy and inexpensive way to increase the number of interconnected nodes on a network. -
Page 13: Different Network Topologies
2. The uplink cable used between both hubs must be a straight-through UTP-5, STP-1 or equivalent twisted-pair cable. 3. If using the uplink jack to uplink with another switch or hub, regular port adjacent to the uplink port must be left free. If the regular port is being used, the uplink jack must be left free. -
Page 14: Other Ways To Expand A Network
How to Configure a Fast Ethernet Network - Multiple-device environment Increasing the size of a network through uplinking will allow a greater number of users to have access to a greater number of services. As explained previously in this manual, two hubs may be uplinked together. While uplinked, each hub's reg- ular jack must be kept free whenever its corresponding uplink jack is being used. -
Page 15: Before The Installation
Chapter 5 - Installing Dual-Speed Hub Before the Installation Before installing a hub, users must make sure that they can provide their net- work with a proper operating environment. An optimal environment for a network must have these features: - Power : The hub must be provided with a power voltage ranging from 100 to 230 VAC (with an error margin of 10%) at 50 to 60Hz (±... -
Page 16: Physical Installation
Chapter 5 - continued Physical Installation The physical location of the hub should be carefully planned. When planning the hub's location, users should pay attention to the following factors: - Ventilation : When installing the hub, users should make sure there are open spaces of at least 10 centimeters both in front and behind the hub. -
Page 17: Connecting Hubs Or Other Devices
Connecting Hubs or Other Devices To make a hub-to-hub connection, do the following: 1. Make sure you have the proper cables: ¥ Use UTP-3, 4, 5 (Unshielded Twisted-Pair) cables or better for 10BASE-T connections ¥ Use UTP-5 or STP-1 cables for 100BASE-TX connections. 2. - Page 18 Speed Hub stack of only two units can easily meet the networking needs of most small to medium-sized workgroups. As your workgroups gradually expand, just add more hubs to your stack, or cascade to another hub or switch using ordinary straight-through cable.

Page 19: Removing The Protective Cover
Removing the Protective Cover This protective cover, on the right side of the hub, is designed to shield the unit from potentially damaging agents that might cause this unit to malfunction or behave erratically if the MII port is exposed. However, when a Dual-Speed Fast Ethernet Hub cascades to another Dual-Speed Fast Ethernet Hub, this protective cover cannot close properly. -
Page 20: Cable Connections
Chapter 5 - continued Cable Connections Once the hub has been correctly mounted as explained before, cables linked to end nodes can be connected to the ports. Caution: While connecting cables to the hub, make sure both the hub and the equipment being connected are turned off. -

first hub's uplink jack. Next, the other end of the cable should be plugged in the other hub's regular jack. To uplink the hub, users should pay attention to the following requirements: - The cable used to uplink both hubs must be a UTP-5, UTP-1 or any equiva- lent cable. -
Page 22: Chapter 6 - Network Management
Chapter 6 - Network Management LED Indicators The hub's front panel contains indicators called light emitting diodes or LEDs. LEDs are used to make a quick diagnostic of the network's status. They allow users to know, at a glance, what problems the network is encountering. Various LEDs, related to different functions, are displayed on the front panel. - Page 23 Chapter 6 - continued - LINK indicators: Color : Green Label : Link One link LED is displayed for each port on the hub. If a device is properly connected to one of the hub's ports, this port's link LED shines steadily.

Page 24: Troubleshooting
- PAR indicator Color : Green Label : Activity The hub possesses one such LED on its front panel. This indicator shines in a steady green when the two nodes are transmitting data at the same time. When a collision occurs, the two end nodes that are attempting to transmit data simultane- ously back off and try again at different time intervals. - Page 25 Chapter 6 - continued Many problems can also be avoided by: - Leaving a free space (10cm at least) in front of the hub's lateral fan. - Keeping the hub away from any electromagnetic interference, light sources, or direct sunlight. - Making sure that all cables, from node to node, do not exceed the recom- mended maximum length of 100 meters.
